F. Water Supply and Drain Connections
WARNING
1. Water supply and drain connections must be installed in accordance with
applicable national, state, and local regulations.
2. Normal operating water temperature should be within 45°F to 95°F (7°C
to 35°C). Operation of the icemaker, for extended periods, outside of this
normal temperature range may affect icemaker performance.
3. To prevent damage to equipment, do not operate the icemaker when the
water supply is off, or if the pressure is below 10 PSIG. Do not run the
icemaker until the proper water pressure is reached.
